Yes, indeed, such functionality can be found in various applications. For example, the heart rate monitor + in the application can measure your heart rate and pressure; all you need to do is put your finger on the camera. You can also measure your heart rate using the Face Pulse app. You can measure the pulse there either from a photograph or just put your finger on the camera. I found a selection of such applications here - https://mirsmartphonov.ru/luchshie-prilozhenija-dlja-izmerenija-pulsa-i-davlenija-na-android/

I don’t know how exactly these applications work, but it seems like the reviews and ratings in the Play Market are not bad.

There are a number of applications, among them:

Runtastic Heart Rate

Instant Heart Rate

Heart Beat Rate

etc.

During heartbeats, blood flow saturates and darkens the skin. If you illuminate your finger with the built-in flash, your phone's camera can capture the differences and calculate the frequency of skin tone changes per minute. The resulting number will be the desired answer - the heart rate.

I personally tried this thing on my friend's Samsung phone, though I was told that I had no heart rate ...
